dude why do you want a 4efte when you can have a beast turbo 5e? making a track car is all about handling and light weight and yeah power but more the case of how you get the power on the tarmac if that makes sense lol i.e power with grip, not power with a shit load of wheel spin, it's not expensive stripping stuff out your car, and with some choice mods a track beast can be fairly simple.
